Fiserv Customer Solutions Associate interview questions

I was looking for a job I could start pretty quickly. Fiserv was running a hiring event for a few training classes they needed to fill. I was able to schedule an interview very quickly. The people interviewing me were very nice, they asked mostly questions from a form. There was no tour our anything like that, the process was pretty quick. I heard back within a couple of days when they made me an offer. The offer was submitted in writing which was good. The interviewers were not necessarily very experienced, or comfortable with interviewing, but that didn't seem to negatively impact my experience. Being for an entry level position, the interview was pretty casual. The HR generalist knew very little about the products I would be supporting, and I wasn't interviewing with the people I would be working for, which surprised me. Basically, I started the job not knowing anything about the job except that it was inbound phones.
